I installed app-text/pandoc 1.9.4.5 after unmasking it. Emerge asked for a lot of other keyword unmaskings including dev-lang/ghc-7.6.2, which I did. I got compilation errors in the following ebuilds (ghc complained the version of the installed libs on which they depended was not right), so I had to unmask them as well. They should probably be listed as a DEPEND with the correct version number, even though I didn't investigate if that should be done in app-text/pandoc or in a dependency of it. These are the ebuild I had to unmask in order to have them compile correctly: =dev-haskell/text-0.11.2.3 ~amd64 =dev-haskell/zip-archive-0.1.2.1-r2 ~amd64 =dev-haskell/cabal-1.14.0 ~amd64
Looking at the exact build failures would be nice. There could be problems like: - incorrect cabal constraints (build bug) - broken library ABIs (fixable by haskell-updater, non-bug) - had-to-comprehend subslot conflicts (portage's misfeature)
